myatari.net has a review of a 68060 add-on board called CT60 which runs at either 66 or 100mhz (depending on processor model) - you can fit 512meg of pc133 ram to it. It also has the exciting 'tip of the day' page.
Also we've just missed Jagfest 2004 in Rochester (12/13June), and the allegro speedhack competition entries are available to download and try out.
